| 摘 要： | 文中基于Midas Soilworks软件,采用强度折减法分析了某公路边坡的稳定性。分析时土体采用Mohr-Coulomb本构模型,对边坡进行有限元分析,得到边坡稳定的最小安全系数,从而判断边坡的稳定性。经过计算,强度折减法的分析结果与极限平衡法分析结果较为接近,具有一致性。但该方法考虑了土体的应力应变关系,更能体现与实际接近的破坏现象,从而提高了分析结果的准确性。经过分析该边坡稳定,无需加固。

| Abstract: | This paper analyzes the stability of a highway slope by strength reduction method via Midas Soilworks software.The Mohr-Coulomb constitutive relationship is used in the analysis for soil and the finite element analysis of the slope is carried out to obtain the minimum safety coefficient of the slope stability,so as to judge the stability of the slope.After calculation,the analysis results of strength reduction method and limit equilibrium method are close and consistent.But this method considers the stress-strain relationship of soil,and can better reflect the damage phenomenon close to the actual,thus improving the accuracy of the analysis results.After analysis the slope is stable and no reinforcement is required. |
